Abstract: An improved flyer assembly for twisting a strand of material in either of two directions and winding the twisted strand of material onto a spool includes a pair of capstans which are rotated about a central axis of the flyer assembly to twist the strand. A floating guide wheel or roller guides the strand from the central axis of the flyer to one of the capstans. Since the direction of rotation of both the flyer assembly and the capstans is reversed when the twist of the strand is reversed, the guide wheel is freely movable between a first position in which the strand is initially fed to one side of a capstan and a second position in which the strand is initially fed to the opposite side of the capstan. If the strand should break during a twisting operation, the end portion of the length of strand leading to the spool is held against one of the capstans by a retainer roller to prevent spilloff and whipping movement of the strand.
